To all whom it may concern:

Be it known that I, Mamiranmra KING, a subject of the King of GreatBritain, residing at the hamlet of Fin erboard, in the county ofVictoria and Province of Ontario, Canada,have invented certain new anduseful- Improvements in Clover-Hullers, of which the following is aspecification.

My invention relates to improvements in clover hullers, and the objectof my invention is to remove refractory bodies, such as stone and iron,from unhulled clover seeds, and my invention will be hereinafterparticularly set forth and described, and what I claim as new will bepointed out in the claims forming part of the specification.

Figure 1 is a vertical longitudinal section through portion of anordinary clover huller, certain parts being shown in side elevation, andFitz. 2 is a-vertieal section on the line as? ri 1. taken longitudinallythroughone end of ortion of a fan or blower, show ing how t a same issupported andconstructed to allow airjto pass thereinto.-

In the drawings like'characters of reference indicate'correspondingparts in each figure m i It must be understood-that myinventionis not confined to use with the type of clover hullerillustrated.

It is well-known that small stxmes and )ieces of iron often pass alongwith the unimlled clover seeds into the huller, resulting in more orless damage to the same. I i

The broad conception of my invention consists in passing a current ofair, re listed to the weight of the hulled clover see s into or througha quantity of the same, as it leaves the conveyer, the seeds beingcarried away by the'currentof air, and the refractorybodies beingremoved by gravity, means-be ing provided for carrying away the currentof air afterit has conveyed. or lifted the unhullcd seeds-to the huller.a

In the embodiment illustratedfof-myl 'n-" vention, as the unhulled seedleaves-the eonveyer, it is blown -by;the-.eurrent1of. air againsta platesupported at an angle,' over' which; it escapes into the huller, theretiree tory bodies passing by gravity; down below sa'idzplate.

C is any suitable sheathing secured to the inner sides of the sills Aand uprights B.

- D is the cylinder mounted by its shaft E on any suitable bearings (notshown), and F isthe throat into which the clover is fed. G is anysuitable beater the shaft H of which is mounted in any suitablebearings, not shown. The said cylinder and beater ass the clover on tothe straw-rack- I which 1s operated back and forth by well-known Thematerial not disposed of by the straw-rack passes therethrouph onto astemmer J positionedj underneath material not disposed of by the saidstemmer passing therethrough onto the convever K. l 1 IL is the huller,of any suitable constructiomend the shaft M thereof is mounted inanysuitable bearings not necessary to Surrounding the huller L is a drumNhavin an opening 0 in its side of the desired wi th,'and extending'fromone end. of the drum to the other. Asis usual,

'the inner side of the drum N is provided with a plurality of rasps Pwhich coact with a -plurality-- of rasps Q carried by the huller L.

It is a plate securedto the drum N and projecting a suitable distancethereabove, andextending from one side of the machine tothe other. Theupper end of this plate R is secured to a support S, secured at each endtothe sides of the machine.

T is a-plate secured by the support U to the stemmer J and dependingtherelielow. The said stemmer is reciproeated horizontally by means ofthe rod V secured to the bottom-2 of. the air-box 3. 4 is a rodconnected to the conveyer K, and by means of the well-known double cranklever 5, the said rods V and 4 are reciprocated to move their connectedparts. Since the plate T coaetsgwith the-plate R, these members areconnected together-by a striploi canvas 6 or other suitable flexiblematerial which will permit of the movement of the plate T and late It soas tmforrrttheiiontWall of an air-chamber 7 leading; directly to theopening 0, and of equal. length: therewith.

The upper endof thisplate issecured to asuppers-10,suitably secured to each sideof the machine.

11 is a plate extendin the full width-of the machine and secure to thesupport 12 supported; at; both; v ends by the mach1neframe. I p v Theplates R and T form one side of the hopper leading to the huller, andthe plates hopper. a I

13 is a drum extending for the full width of the machine, the same beingrovided on one'side and for its whole lengti with a 15 are rings aroundwhich each end of the drum is secured, and these rings (only one ofwhich is shown) are secured by the nuts and boltsdesignated by thecommon numeral of reference 16 to the sheathing C. The said sheathingCis provided with an opening 17 of the same size and in aline ment withthe opening 18 formed in the 19 are any suitable spiders carried by theframe oi-the machine 1n which has bearing the'shaft QO-on which ismounted the'ar'ms 21 of bars 22forming a blower or fang-At each forwardmovement of the conveyer K,

Ihe strength of thecurrent of-ninescaping from the spout l l will carrythe unhu le cloverseeds in the' direction de'-' scribed, and the refractory: bodies' will'be 11 and to 'fall'down on-to the fioor floysomebeing carried up withthe-seed andgde'posited in the cha'tier; and others falling' into the"corner 32 a Carried I by the support 10 is} a plate '33 which extends*forwthe full? width of the machine i and isof sufiicientlength toi,prevent the bodies of retractory qmateriat assing through the opening 0into the iiuller L. As iswell-known', the chat? has .to be assed severaltimes through the huller :L an ,anyof therefractory bodies that aregassed into the cha'fler 27 are in due course s1 eposited onthe conveyerand separated from the unhullcd seeds after the manner before set.-forth.

34 is the usual blower or fan mounted within'the drum 35' whereby acurrent of ,air is assed through the chafi'er 27.

The ottom 2 of the air-box 3 extends for ;-t-he'full width of thestemmer J and the same is secured by the nuts and bolts designated bythe common numeral of reference 36 to the end boards 37 which are alsosccured by the said means to the said stemmer. As the bottom 2 is spacedapart from the bottom of the stemmer J, a passageway is formed betweenthese members through which the current of air may cscape rom theair-chest 7.

' I From my experiments, I have found that it is absolutely essential toprovide some 'meansfor permitting the esca 'e of the current of airafter it has carrie the unhullcd clover-seed to the huller'L, because ifthe air-box B'or its equivalent be not provided, the he or leading tothe huller would beicome h ed with air and consequently the Qfanor-blower mounted in the drum 13 could not ass more thereinto andconsequently Fth'e evice would not be operative.

The 'top'of the plate 11 is spaced far enough apart from-the bottom 2 ofthe air- -box,' so as'to provide a space of sufiicient width to permit ablast of air from the drum -13 to convey the unhullcd clover seed intothe hopper leading-to'the huller. 'The unhulled seed is blown againstthe bottom 2 and is deflected downward into the hopper leading to thehuller. It will be therefore understood by one skilled in this art, thatthe construction already described causes the unhulled seed to dro intothe huller, and permits the current 0 air which carried said seed'into'the hop er leading to said huller,-to escape from t e to of said hopper'to the forward end 0 the machine through the air-box 3. The floor ofthis air-box separates thecurrent of air passing into the said hopperfrom the drum i3, and the current of air escaping from the top of saidhopperfrom said air-box, and therefore these two currents of air cannotconflict. Without the presence of'the said air-box, there-would'beno'distinctive current of air gassing fromthe hopper leadin to the saidullery-and consequently in order that my invention-maybe operative thesaid airbox or itsequivalent must be rovided. .From' the fore oingspeciication it is clearto-one-slrille in this art that thecurpassing'betw'een the-sem'e endthe drum -13 ,rent off air: forced outof the drum 13 through -theunhulled'clover seed as it passes from theconveyer K, absolutely separates all refractory bodies from the seed,thereby preventing the damaging of the huller L from this source.

My invention can be applied to existin clover hullers, and fromexhaustive expenmonts carried on under practical conditions with my ownclover huller, I find that the same is certain in its operation.

The straw-rack I, stelnmer J and conveyer K are suspended by the usuallink-rods a from the frame of the machine. The plates R and 11 areprovided respectively with slots 0 and (1 through which ass the rod 4,and the plate T is also provi ed with a slot e (shown dotted) throughwhich the rod V operates.

\Vhile I have described what I consider to be the best embodiment of myinvention, I desire it to be understood that the principle can beembodied in different forms, and I desire not to be limited beyond therequirements of the prior art and the terms of my claims.

What I claim as my invention is:

In a clover-huller, the combination with the conveyer; means foroperating the same; the huller operating within its drum,and a suitablehopper for said huller,-of a plate supported beyond the front end ofsaid conveyer and positioned at the re uired angle; a blowerfunctionally intermediate the front of said conveyer and the said plate,whereby a current of air is blown through the unhulled clover seed as itpasses from said conveyer, blowing the same against and over said plateinto the hopper leading to said huller, and means for ermitting theescape of the air from said opper, as set forth and for the urpose secified.

2. In a c over-hul er, the combination with the conveyer; means foroperating the same; the huller operating within its drum, and a suitablehopper for said huller, of a plate supported beyond the front end ofsaid conveyer and positioned at the required angle; a lower functionallyintermediate the front of said conveyer and the said plate, whereby acurrent of air is blown through the unhulled clover as it passes fromsaid conveyer, blowing the same against and over said plate into thehopper leading to said huller; means for permitting the escape of theair from said hop er, and a plate supported by said machine etween saidblower and said huller whereby the refractory bodies asthey'areseparated from the unhulled clover are prevented from passinginto said huller.

3. In a' clover huller, the combination with the st'emmer; means foroperating the same; the conveyer; means for operating the same, and thehuller, operating within its drum, of a drum open at each end to permitthe necessary air supply, supported within said machine, .and providedwith a discharge spout; means within said drum for creating a current ofair; a late supported at an upward-outward ang e by sald machine inadvance of the front end of said conveyer and the discharge s out of thesaid drum; a hopper for said hul er; a plate positioned intermediatesaid drum and said huller to prevent the passage of the separated bodiesof refractory material into said huller, and an air-box carried by saidstemmer, whereby the current of air escapes from the upper part of thehopper for said huller, the who e being arranged and set forth for thepurposes specified.

4.-.' In a clover huller, the combination with the stemmer; means foroperating the same; the conveyer; means for operating the same, and thebullet, operating within its drum, of a drum open at each end to permitthe necessary air supply, supported within saidmachine and rovided witha discharge spout; means within said drum for creating a current of air;a plate supported at an upward-outward angle by said machine in advanceof the front end of said conveyer and the dischargespout of the saiddrum; a hopper for said huller, the same provided with a forwardflexible wall which is supported at its upper end by said stemmer; alate ositioned intermediate said drum an said iuller to prevent thepassage of the separated bodies of refractory material into said huller,and an air-box carried by said stemmer, whereby the current of airescapes from the upper art of the hopper for said huller, the who ebeing arranged as set forth and for the purpose speclfied.
